Self-adjusting Locksmith Tool with Dynamic Threaded Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locksmith tools are cumbersome, unreliable, and prone to mechanical damage when dealing with complex locks featuring randomly oriented code plates, leading to inefficient and potentially destructive unlocking processes.
Innovation Solution
A self-adjusting locksmith tool with a handle and decoding end piece featuring a carrier with longitudinal openings, perpendicular pins, and two pumping elements that allow independent rotation and axial displacement, along with guides and pin holders that accommodate differently oriented code plates, eliminating the need for a pusher and enhancing tool strength and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional locksmith tools with direct bolt connections are used, then the structure is simple, but the tool cannot rotate relative to the decoding end piece and may self-unwind
Solution Approach 1:
The patent replaces static bolt connections with a dynamic threaded connection system that allows controlled rotation. The swirl rotates relative to the decoding end piece through threaded engagement with the puller, enabling dynamic adjustment while preventing self-unwinding through friction and thread geometry.
Solution Approach 2:
The patent introduces a puller as an intermediary element between the swirl and the decoding end piece. The puller mediates the connection by engaging with both the swirl and the decoding end piece, allowing rotation while preventing self-unwinding through its threaded engagement with the swirl.
2Reliability
If U-shaped pumping elements with complex wavy profiles are used, then the decoding function is achieved, but the durability of the product is reduced
Solution Approach 1:
The patent segments the pumping element into simpler geometric components rather than using a single complex wavy profile. The pumping element is divided into distinct sections with simpler curves, reducing stress concentration points and improving durability while maintaining the decoding function.
3Adaptability or versatility
If side lifters and multiple holders are added to the tool, then the decoding capability is improved, but the operation becomes more complicated
Solution Approach 1:
The patent merges the functions of side lifters and multiple holders into an integrated carrier structure. The carrier combines multiple functional elements into a single unified component that performs decoding operations without requiring separate manipulation of multiple independent parts, simplifying the operation while maintaining versatility.
4Adaptability or versatility
If the tool is designed to accommodate randomly oriented code plates, then the adaptability increases, but the tool length and weight increase making it more inconvenient to operate
Solution Approach 1:
The patent employs dynamic positioning mechanisms that allow the code plates to be oriented in different directions without requiring multiple fixed-position plates. The carrier and pumping elements can rotate and adjust to accommodate various orientations, reducing the need for additional weight to support multiple fixed configurations.
